CAS TSIS MUAJ. {18979-61-8 butylresorcinol
Lub cev muaj zog thiab nyab xeeb & tawv nqaij pleev xim rau tus neeg sawv cev
4- butylresorcinol yog cov tshuaj ntxuav hniav dawb thiab tawv nqaij tawv nqaij tus yam ntxwv ntawm kev ua tau zoo thiab kev nyab xeeb ntawm daim tawv nqaij.
Hyperpigmentation yog vim Melanin tsub zuj zuj, uas tuaj yeem tshwm sim vim tias muaj kev laus lossis kev tsis sib haum xeeb zoo li Melasma. Cov kev tswj hwm tseem ceeb ntawm Melanin ntau lawm yog qhov enzime tyrosinase, thiab yog li cov enzime yog lub hom phiaj tseem ceeb tshaj plaws rau txhua tus neeg sawv cev whitiling.
